' reference to. that form of mounting in which ad ustable means are employed for lnsurlng correct positioning of the mounting on the face and additional holding means are em-v ployed for securing the mounting in position.

One of the particular objects of our invention is the provision of an improved mounting of the pince-nez type which shall be neat and attractive in appearance and shall occupy a minimum amount of space between the lenses compatible with "the nose of the wearer, thus allowing the lenses to fit close to the nose and increase the field of vision of the wearer.

Further objects of our invention include the provision of an ophthalmiczmounting which may be readily adjusted to comfortably yet securely fit and yet engage the nose and a general simplification of the details of construction of mountings of this character whereby the same may be readily produced in large quantities.

Other objects and advantages of our improved mounting should be readily apparent by reference to the following description taken in connection with the accompanying drawings, and it will be understood that we may make any variations or modifications in Y the specific detailsof construction shown and described within the scope of the appended claim without departing from or exceeding the spirit of our invention.

another variation. Fig. X represents a plan v ew of Fig. IX. Fig. XI represents a plan view of another form of our invention. Fig.

In the drawings, inwhich similar charac larly illustrated in Fig. II, we have shown the arched-portion 3 of the bridge connected to the lens attachment 2 by means of a post 4L, the bridge continuing downward below said post in the portion5 looped and extending upwardly in the guard 6, said guard,

however, being preferably disposed below the post 4. This guard thus provides a weight supporting member which may be adjusted by bending the looped portion 5 of the bridge. To balance the mounting on the face and retain the same in position, we securev to" the post 4, as by means of the p1vot1'0, a gripping member 7, preferably actuated as by a spring 8,'to swing inward and gripthe upper part of the nose.

In Figs. III and IV, wehave shown a slight variation of our invention, in which the terminal portion of the bridge 3 is split,

one arm being continued downward and looped to form the guard 6, said arm being flattened or reduced to provide a satisfactory bearing portion, while the other arm 4: extends outwardly and is suitably secured to the lens attachment, as indicated. This'arm I serves as a support for the gripping member in the same way as the post 4 previously described. I

I11 Figs. V and VI, we have shown another form of our invention, in this form the bridge being likewise split to provide a pair of arms at each end thereof, both of said arms, however, being formed into looped or bearing portions 6, the ends of said arms extending upwardly and being bent outwardly to engage the lens attachment 2, said arms thus forming both the guard and the connecting portion 4: as

will be best understood by reference to Fig. VI.

In Figs. VII and VH1, we have shown another variation in which the arched portion 3 of the bridge is outwardly looped in the part 1- for engagement with the lens attachment, and is then continued from said loop downward in a second larger loop forming the guard portion 6,

In Fig. IX, in place of employing the neck or connecting portion 4i, the arch of the bridge is shown as connected directly to the lens attachment, being extended therebeyond and reversely bent to bring the guard portion 6 substantially in line with or slightly forward of the lens attachment, while the guard or gripping member 7 is secured to the lens attachment above the connection of the bridge thereto.

In Figs. Kl: and X11, wehave illustrated a form quite similar to that just described, with the exception that the bridge in place of being connected to the lens attachment direct has an offset 8 formed therein, which provides a seat for the gripping member 7, the construction being otherwise substan tially the same.

In that form of our invention illustrated in Figs. Kill to XV inclusive, we have employed not only a slightly different detailed construction, but also a different method of operation of the mounting, in that the bridge arch 3 is continued rearwardly past its point of attachment to the lenses, an eye or loop 9 providing a seat for the pivot or guard attaching member 10, the material of the bridge being then continued forward in an arm bearing a suitable nose engaging member 6. i e would call particular attention, however, to the fact that in this form of mounting the seat 9, and consequently the pivot 10, are outwardly inclined so that the pivots slope or diverge from each other. The advantage of this construction will probably be best understood by reference to the dotted lines in Figs. XIII and XV, from which it will be seen that pressure on the handles 11 of the gripping member arms 7 to draw said handles together and open the guards will cause the arms to ride upwardly along the arch of the bridge, a much narrower P. D. being thus attained, in that it is not necessary to provide sutlicient space between the arch or crest of the bridge and the lens attachment to allow for the play of the lever, as has hitherto been generally deemed essential. vantage in saving of space, a novel method of gripping the nose is attained, in that as the gripping members come inward into operative engagement with the nose their movement is not only inward but also slightly upward, thus moving up into engagement with the orbital arch at the top of the nose and forcing the mounting slightly downward on the nose, the position of the guards then preventing any upward slipping of the mounting tending to loosen the same, and also holding the lower weight supporting members 6 in better engagement with the nose and relieving the mounting of the liability to swing forward at the bottom, which might otherwise occur where the same merely rested on the nose and the upper pads allowed to grip the same.

A mounting of the character described, comprising a bridge having its terminal portions looped to provide guards, lens attachments intermediately secured to the bridge, and automatic gripping means carried by one of the two first named parts and operating above the guard portions of the bridge.

In testimony whereof we ah'iX our signatures in presence of two witnesses.
